B1. Step Up

Grab a pair of dumbbells and stand up to 2 feet from a step or exercise bench, with weights at your sides and feet hip-width apart. Place your left foot on the step (A) and press up through the leg. Allow your right leg to come up and brush the bench (B), but don't put any weight on it. Step down with your right leg, then your left. Complete all reps, then repeat, stepping up with your right leg. That's 1 set. Go to B2.
